Description

Technical Field

[0001] This utility model relates to the technical field of injection molding machine clamping equipment, and in particular to a column-free clamping device and compression molding equipment. Background Technology

[0002] In injection molding, mold clamping is a crucial step that directly affects the quality of plastic parts, production efficiency, and equipment safety. Mold clamping refers to the injection molding machine using a clamping mechanism to tightly close the fixed mold and moving mold, and applying sufficient pressure to resist the expansion force generated when molten plastic is injected into the mold cavity during the injection stage. This prevents the mold from being pushed open, which could lead to problems such as overflow and deformation of the plastic parts. In conventional four-column injection molding machines, the mold is placed between four columns, which limits the operating space and reduces the applicability of the mold. It also makes it difficult to form an automated production line with automated equipment.

[0003] A related technology provides a C-type mold clamping mechanism and injection molding machine, which increases the operating space. Its overall structure is a C-shaped frame with fixed and moving mold plates distributed vertically on the frame. A mounting cavity is provided below the moving mold plate in the frame, housing a mold-locking drive component and multiple quick-closing drive components arranged around the outer periphery of the mold-locking drive component. The quick-closing drive component drives the moving mold plate, causing it to close or open with the fixed mold plate. The mold-locking drive component locks the moving mold plate when it closes with the fixed mold plate, improving the applicability of the mold. However, because the frame is a one-piece design, it is subjected to eccentric loads during the mold-locking process, increasing the risk of frame deformation and shortening its service life. Since the frame cannot be replaced, when the deformation reaches a critical state, it will fail, leading to the scrapping of the mold clamping mechanism, causing production stoppage and reduced production efficiency.

[0029] The beneficial effects of this utility model are:

[0030] This utility model provides a column-free mold-locking device and a compression molding equipment. The column-free mold-locking device includes a body unit and an opening and closing mold unit. The body unit includes a first support member, a second support member, and a first connecting member. The first support member and the second support member are arranged sequentially along the vertical direction. The second support member is fixedly installed.

[0031] During mold closing operations, the mold is placed on the second support member, and the output end of the mold opening and closing unit approaches the second support member vertically until the upper and lower molds are initially in contact. Because the projection of the enclosed area of ​​the output end of the mold opening and closing unit onto the second support member does not coincide with the projection of the enclosed area of ​​the first connecting member onto the second support member, there are no other structures between the output end of the mold opening and closing unit and the second support member.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] This embodiment provides a column-free mold-locking device, such as Figure 1 and Figure 2As shown, the device includes a body unit 1 and a mold opening and closing unit 2. The body unit 1 includes a first support member 11, a second support member 12, and a first connector 14. The first support member 11 and the second support member 12 are arranged sequentially in the vertical direction. The second support member 12 is fixedly installed. The first end of the first connector 14 is fixedly connected to the first support member 11, and the second end of the first connector 14 passes through the second support member 12 and is fixedly installed. The second support member 12 and the first connector 14 are slidably connected. The mold opening and closing unit 2 is fixedly installed. Its output end can approach the second support member 12 in the vertical direction and can slide and be fixedly connected to the first support member 11 through the locking unit 4. The space between the output end of the mold opening and closing unit 2 and the second support member 12 is used to place the mold. In the vertical direction, the projection of the enclosed area of ​​the output end of the mold opening and closing unit 2 onto the second support member 12 does not coincide with the projection of the enclosed area of ​​the first connector 14 onto the second support member 12.

[0050] During mold closing operation, the mold is placed on the second support member 12, and the output end of the mold opening and closing unit 2 approaches the second support member 12 in the vertical direction until the upper and lower molds are initially fitted together. Since the projection of the enclosed area of ​​the output end of the mold opening and closing unit 2 onto the second support member 12 does not coincide with the projection of the enclosed area of ​​the first connecting member 14 onto the second support member 12, there are no other structures between the output end of the mold opening and closing unit 2 and the second support member 12. This ensures unobstructed loading, unloading, and maintenance of the mold, increasing the operating space. Furthermore, the body unit 1 adopts a split design, facilitating targeted replacement of the body unit 1 and reducing the maintenance cost of the column-free mold locking device. It should be noted that in this embodiment, the first end of the first connecting member 14 is connected to the first support member 11 by a nut. In other embodiments, the first end of the first connecting member 14 is welded to the first support member 11, or the first end of the first connecting member 14 is bonded to the first support member 11, etc. No restrictions are imposed here.

[0051] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, both the first support member 11 and the second support member 12 are plate-shaped structures. In other embodiments, both the first support member 11 and the second support member 12 are block-shaped structures, or the first support member 11 is a support frame structure and the second support member 12 is a block structure, etc. No limitations are imposed here.

[0052] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the first connector 14 is a tie rod. Tie rods offer both high-strength support and high-precision guidance, while also being highly adaptable, easy to maintain, and cost-effective. In other embodiments, the first connector 14 can also be a square column, etc. No limitations are imposed here.

[0053] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, four first connectors 14 are provided, divided into two groups. The two groups of first connectors 14 are arranged parallel to each other in the left-right direction, and the two first connectors 14 in each group are arranged parallel to each other in the front-back direction. The arrangement of multiple first connectors 14 improves the connection stability and force balance of the first support 11, and enhances the sliding fit between the second support 12 and the first connectors 14. In other embodiments, one, two, three, or five first connectors 14 are provided, etc. No limitation is made here.

[0054] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the two sets of first connecting members 14 are symmetrically arranged along the centerline of the first support member 11 in the front-rear direction. This ensures balanced force distribution and avoids deformation of the component due to force on one side. In other embodiments, the arrangement of the two sets of first connecting members 14 is not limited.

[0055] Optionally, such as Figure 1 and Figure 2 As shown, the fuselage unit 1 includes a third support member 13, which is located below the second support member 12. The second end of the first connector 14 is fixedly connected to the third support member 13. The columnless molding device includes a molding unit 3, which includes a molding assembly 31. The molding assembly 31 is located on the third support member 13 and can drive the third support member 13 to move in the up and down direction. By fixing the second end of the first connecting member 14 to the third support member 13, the first support member 11, the four first connecting members 14, and the third support member 13 form a rigid integral structure of the machine body. Simultaneously, the mold-locking assembly 31 can drive the third support member 13 to move vertically. When the mold-locking assembly 31 drives the third support member 13 downwards, and the output end of the mold-opening and closing unit 2 is fixedly connected to the first support member 11 via the locking unit 4, since the first support member 11 forms an integral unit with the first connecting member 14 and the third support member 13, the first support member 11 moves downwards simultaneously. This causes the upper end of the mold to be subjected to a downward force from the output end of the mold-opening and closing unit 2, and the lower end of the mold to be subjected to an upward force from the second support member 12, thus achieving the mold-locking operation and providing a stable structural foundation for subsequent injection molding. It should be noted that the third support member 13 is a support plate. In other embodiments, the third support member 13 can also be a support block or a support frame, etc. No limitation is made here.

[0056] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the second end of the first connector 14 is connected to the third support 13 via a nut. In other embodiments, the second end of the first connector 14 is welded to the third support 13, etc. No limitations are imposed here.

[0057] Optionally, such as Figure 1 and Figure 2 As shown, the mold-locking assembly 31 is fixedly connected to the third support member 13, and the output end of the mold-locking assembly 31 is fixedly connected to the second support member 12. This arrangement allows for power transmission between the third support member 13 and the second support member 12, avoiding the need for other support structures to lock the mold, and thus improving the integrity and independence of the column-free mold-locking device.

[0058] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the mold-locking assembly 31 is threadedly connected to the third support member 13, and the output end of the mold-locking assembly 31 is threadedly connected to the second support member 12. In other embodiments, the mold-locking assembly 31 is snap-fitted to the third support member 13, the output end of the mold-locking assembly 31 is connected to the second support member 12 via a gear and rack structure, or the mold-locking assembly 31 is bonded to the third support member 13, and the output end of the mold-locking assembly 31 is connected to the second support member 12 via a cam structure, etc. No limitations are imposed here.

[0059] Specifically, such as Figures 1-4 As shown, in this embodiment, the mold-locking assembly 31 includes two mold-locking components 311, which are arranged parallel to each other in the left-right direction. In other embodiments, the mold-locking assembly 31 may also include three or four mold-locking components 311, etc. It should be noted that the output end of the mold-locking component 311 is threadedly connected to the second support member 12. No limitation is made here. It should be noted that in this embodiment, the mold-locking component 311 is a mold-locking cylinder. In other embodiments, the mold-locking component 311 may also be a hydraulic cylinder, etc. No limitation is made here.

[0060] Optionally, such as Figures 1-4 As shown, the mold-locking unit 3 also includes a balancing component 32 and a connecting component 33. The balancing component 32 is fixedly disposed on the third support member 13. Along the front-back direction, the balancing component 32 is located on one side of the first connecting member 14. The mold-locking component 31 and the output end of the mold-opening and closing unit 2 are located on the other side of the first connecting member 14. The connecting component 33 is fixedly connected to the output ends of the first support member 11 and the balancing component 32. The second support member 12 is slidably connected to the connecting component 33.

[0061] When the mold is locked, the two locking components 311 are activated simultaneously, causing the second support component 12 to move upward. At this time, the second support component 12 is subjected to force on one side. The balancing component 32 and the connecting component 33 are set up, and along the front-back direction, the balancing component 32 and the locking component 31 are located on both sides of the first connecting component 14. With the first connecting component 14 as the support point, a balancing force is applied to the first support component 11 from the side opposite to the locking component 31. The magnitude of this force matches the unilateral force of the locking component 311, and the direction is opposite, which just cancels the tilting trend and finally keeps the first support component 11 in a horizontal state, eliminating the eccentric load of the first support component 11. The balancing component 32 eliminates the eccentric load of the first support 11 by dynamically providing balancing force. This ensures the motion accuracy during mold clamping and avoids wear or deformation of the first support 11 or connecting component 33 due to long-term eccentric stress. The connecting component 33 provides sliding guidance for the second support 12 and can also share part of the load through its own rigidity. Together with the balancing component 32, it more stably counteracts the eccentric load and avoids structural deformation due to uneven stress.

[0062] Specifically, such as Figure 3 As shown, in this embodiment, the first connector 14 is located at the exact center of the balancing assembly 32 and the mold-locking assembly 31 along the front-to-back direction. When there is an interaction force between the balancing assembly 32 and the mold-locking assembly 31, the centrally located first connector 14 can more evenly distribute the stress, reduce local wear, and the symmetrical layout helps to improve the stability of the overall structure. In other embodiments, the first connector 14 is located in the middle of the balancing assembly 32 and the mold-locking assembly 31, close to the balancing assembly 32, or the first connector 14 is located in the middle of the balancing assembly 32 and the mold-locking assembly 31, close to the mold-locking assembly 31, etc. No limitations are imposed here.

[0063] Specifically, such as Figures 1-4 As shown, in this embodiment, the balancing assembly 32 includes two balancing elements 321. In other embodiments, the balancing assembly 32 includes three or four balancing elements 321, etc. No limitation is made here. It should be noted that in this embodiment, the balancing element 321 is a mold-locking cylinder. In other embodiments, the balancing element 321 is a hydraulic cylinder, etc. No limitation is made here.

[0064] Specifically, in this embodiment, the connecting assembly 33 includes two second connecting members 331. One end of each of the two second connecting members 331 is connected to the output end of the balance member 321 by a screw, and the other end of each of the two second connecting members 331 is threadedly connected to the first support member 11. In other embodiments, the connecting assembly 33 includes three or four second connecting members 331, etc. No limitation is made here. It should be noted that in this embodiment, the second connecting member 331 is a piston rod. In other embodiments, the second connecting member 331 can also be a guide bar, etc. No limitation is made here.

[0065] Specifically, such as Figures 1-4 As shown, in this embodiment, the two locking members 311 and the two balancing members 321 are distributed at the four corners of the third support member 13. This corner distribution allows for more even force distribution, ensuring the stable operation of the overall structure. In other embodiments, the two locking members 311 and the two balancing members 321 are distributed at other locations on the third support member 13. No restrictions are imposed here.

[0066] Optionally, such as Figure 1 As shown, the mold opening and closing unit 2 includes a support component 23 and a drive component 21. The support component 23 is fixedly connected to the second support member 12, and the drive component 21 is disposed on the support component 23. The output end of the drive component 21 is a pressing member 22. Along the front-to-back direction, the first connecting member 14 and the pressing member 22 are located on opposite sides of the support component 23. With the support component 23 as the intermediate reference, the first connecting member 14 is located on the rear side of the support component 23, and the pressing member 22 is located on the front side of the support component 23. This arrangement ensures that the first connecting member 14 avoids the operating area of ​​the mold, i.e., the area where the pressing member 22 moves vertically, allowing for unobstructed loading, unloading, and maintenance of the mold, providing more operating space and optimizing space utilization. It should be noted that in this embodiment, the support component 23 is welded to the second support member 12. In other embodiments, the support component 23 is threaded to the second support member 12, etc. No limitations are imposed here.

[0067] Specifically, in this embodiment, the support component 23 is a square frame structure formed by welding four I-beams. In other embodiments, the support component 23 is a U-shaped structure formed by welding three support blocks, and the bottom end of the U-shaped structure is fixedly connected to the second support member 12, etc. No limitations are imposed here.

[0068] More specifically, such as Figure 1As shown, in this embodiment, along the vertical direction, the projections of the enclosed areas of the four first connectors 14 onto the second support 12 and the projections of the pressing member 22 onto the second support 12 are located on both sides of the support assembly 23 along the front-back direction. In other embodiments, along the vertical direction, the projections of the enclosed areas of the four first connectors 14 onto the second support 12 and the projections of the support assembly 23 onto the second support 12 do not coincide, and the projections of the pressing member 22 onto the second support 12 and the projections of the support assembly 23 onto the second support 12 partially coincide, etc. No limitations are imposed here.

[0069] Specifically, such as Figure 1 and Figure 4 As shown, in this embodiment, the driving component 21 includes a mounting component and a mold opening / closing driving component. The mounting component is fixedly connected to the support component 23, and the mold opening / closing driving component is threadedly connected to the mounting component. A pressing component 22 is fixedly connected to the output end of the mold opening / closing driving component, which can drive the pressing component 22 to reciprocate in the vertical direction. The action of the mold opening / closing driving component drives the pressing component 22 to move up and down, thereby realizing the opening or closing of the mold. It should be noted that in this embodiment, the mounting component is a mounting bracket. In other embodiments, the mounting component is a mounting block or mounting plate, etc. No limitation is made here. Specifically, in this embodiment, the mounting component is welded to the support component 23. In other embodiments, the mounting component is snap-fitted to the support component 23, etc. No limitation is made here.

[0070] Specifically, such as Figure 1 and Figure 4 As shown, in this embodiment, the mold opening and closing drive is a hydraulic cylinder. In other embodiments, the mold opening and closing drive can also be a pneumatic cylinder or a linear motor, etc. No limitation is made here. More specifically, in this embodiment, the output end of the mold opening and closing drive is threadedly connected to a pressing member 22. In other embodiments, the output end of the mold opening and closing drive is plugged into a pressing member 22, etc. No limitation is made here.

[0071] Specifically, such as Figure 1 and Figure 4 As shown, two mounting components and two mold-opening / closing drive components are provided. These two components are positioned on both sides of the support assembly 23 along the left-right direction, and the output ends of both mold-opening / closing drive components are threadedly connected to the pressing component 22. This arrangement ensures that when the pressing component 22 approaches the second support component 12, the two mold-opening drive components on both sides can generate symmetrical and synchronous driving forces. This effectively avoids tilting or offset of the pressing component 22 caused by unilateral driving, ensuring that the pressing component 22 always maintains parallelism with the second support component 12. It also ensures that the pressing component 22 experiences uniform force on all parts during the approach process, thereby guaranteeing the accuracy and stability of the pressing action.

[0072] Optionally, such as Figure 2 and Figure 3 As shown, in this embodiment, the mold opening and closing unit 2 includes a support assembly 23 fixedly connected to the second support member 12 and a drive assembly 21 disposed on the support assembly 23. The output end of the drive assembly 21 is the pressing member 22. The columnless mold locking device also includes a first guide unit 5, including a slidingly connected guide rail 51 and a slider 52. The guide rail 51 extends in the vertical direction. One of the guide rail 51 and the slider 52 is disposed on the support assembly 23, and the other is disposed on the pressing member 22. The slidingly connected guide rail 51 and slider 52 serve as guides for the pressing member 22 to move towards the second support member 12. Firstly, they guide the pressing member 22 to move along a preset trajectory, ensuring the stability and smoothness of the pressing member 22 during the mold closing process. Secondly, they prevent uneven molds from causing the output end of the mold opening and closing drive to deviate from its path, which could lead to uneven pressing force or mold closing errors.

[0073] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the guide rail 51 is fixedly connected to the support assembly 23, and the slider 52 is disposed on the pressing member 22. In other embodiments, the guide rail 51 is fixedly connected to the pressing member 22, and the slider 52 is disposed on the support assembly 23. No limitation is imposed here.

[0074] It should be noted that in this embodiment, the guide rail 51 is threaded to the support assembly 23, and the slider 52 is welded to the pressing member 22. In other embodiments, the guide rail 51 is snap-fitted to the support assembly 23, and the slider 52 is integrally formed with the pressing member 22, etc. No limitations are imposed here.

[0075] Optionally, such as Figure 1 and Figure 3 As shown, in this embodiment, the columnless mold-locking device further includes a second guide unit 6, comprising a guide post 61 and a linear bearing 62 slidably connected. The guide post 61 extends in the vertical direction, and one of the guide post 61 and the linear bearing 62 is disposed on the first support member 11, while the other is disposed on the pressing member 22. When the mold-opening and closing drive member moves the pressing member 22 in the vertical direction, the presence of the guide post 61 and the linear bearing 62 further ensures that the pressing member 22 does not deviate when moving in the vertical direction, ensuring the accuracy of the mold-opening and closing action. Moreover, the guide post 61 and the linear bearing 62, as the guide structure of the columnless mold-locking device, prevent a decrease in guide stability.

[0076] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the guide post 61 is fixedly connected to the pressing member 22, and the linear bearing 62 is disposed on the first support member 11. In other embodiments, the guide post 61 is fixedly connected to the first support member 11, and the linear bearing 62 is disposed on the pressing member 22. No limitation is imposed here.

[0077] Specifically, in this embodiment, the guide post 61 is threaded to the pressing member 22, and the linear bearing 62 is embedded in the first support member 11. In other embodiments, the guide post 61 is welded to the pressing member 22, and the linear bearing 62 is embedded in the first support member 11, etc. No limitation is made here.

[0078] Optionally, such as Figures 5-7 As shown, in this embodiment, the locking unit 4 includes a locking drive 42 and two locking components 41 arranged at intervals in the left-right direction. One end of each locking component 41 is disposed on the first support 11, and the other end of each locking component 41 is fixedly connected to the pressing member 22. The locking drive 42 is disposed between the two locking components 41 in the left-right direction. The locking drive 42 includes two output ends disposed opposite to each other in the left-right direction. The first output end of the locking drive 42 is drivenly connected to one end of one of the locking components 41, and the second output end of the locking drive 42 is drivenly connected to one end of the other locking component 41. The mold opening and closing drive is activated, moving the pressing component 22 towards the second support component 12. Once the upper and lower molds are initially engaged, the locking drive 42 is activated, simultaneously fixing one end of the locking assembly 41 to prevent further movement, thus maintaining the positions of the pressing component 22 and the first support component 11. This drive-fixing process achieves position locking between the pressing component 22 and the first support component 11, ensuring the pressing component 22 is locked in a critical direction and improving the flexibility of the column-free mold locking device. In other embodiments, the locking unit 4 may have one locking assembly 41, with one end of the locking assembly 41 attached to the first support component 11 and the other end fixedly connected to the output end of the mold opening and closing unit 2. The locking drive 42 may be fixedly attached to the first support component 11, with its output end connected to one end of the locking assembly 41 and capable of fixing that end. Alternatively, the locking unit 4 may have three locking assemblies 41, etc. No limitation is imposed here. It should be noted that, in this embodiment, one output end of the locking drive 42 is connected to one end of a locking assembly 41 via a connecting rod, and the other output end of the locking drive 42 is connected to one end of another locking assembly 41 via a pin. In other embodiments, both output ends of the locking drive 42 are fixedly connected to one end of each of the two locking assemblies 41, etc. No limitations are imposed here.

[0079] Specifically, in this embodiment, the locking drive 42 is a cylinder. In other embodiments, the locking drive 42 may also be a linear motor or a double-acting cylinder, etc. No limitation is made here.

[0080] Specifically, such as Figures 5-7As shown, in this embodiment, the locking assembly 41 is a combination of a brake nut and a brake screw. Since the structure and working principle of the brake nut and brake screw are existing technologies, they will not be described in detail here. In other embodiments, the locking assembly 41 may also be a combination of a wedge block and a column with a wedge groove, or the locking assembly 41 may also be a locking pin and a locking post with multiple spaced locking holes, etc. No limitations are imposed here.

[0081] Specifically, such as Figures 5-7 As shown, two locking components 41 are provided, spaced apart in the left-right direction. A locking drive 42 is connected to one end of each locking component 41. The locking unit 4 also includes a linkage component 43, which is positioned between the two locking components 41 and rotatably connected to one end of each component. The linkage component 43 can drive the two locking components 41 to be synchronously fixed. The linkage component 43 ensures the consistency of the actions of the two locking components 41, improving the working stability and reliability of the locking unit 4.

[0082] Specifically, in this embodiment, the linkage assembly 43 includes a linkage disc, a first linkage rod, and a second linkage rod. The first linkage rod is rotatably connected to the linkage disc and one of the brake nuts, and the second linkage rod is rotatably connected to the linkage disc and the other brake nut. This allows the first and second linkage rods to smoothly transmit torque under the action of the linkage disc, ensuring the linkage between the first and second linkage rods and guaranteeing stable drive for the two brake nuts during synchronous operation. In other embodiments, the linkage assembly 43 can also be a gear linkage, a gear-rack and pinion mechanism, or a linkage mechanism, etc. No limitations are imposed here.

[0083] This embodiment also provides a compression molding equipment, including an equipment body and a column-free mold-locking device, which is mounted on the equipment body. By applying the column-free mold-locking device, there is no obstruction during mold loading and unloading and maintenance, increasing the operating space and facilitating targeted replacement of the machine body unit 1, thereby reducing maintenance costs.

[0084] The following is combined with Figures 1-7 The working principle of the columnless mold-locking device is explained as follows:

[0085] When the mold is locked, the mold is placed on the second support member 12. The mold opening and closing drive is activated, which drives the pressing member 22 to move downward until the upper mold and the lower mold are initially in contact. Then, the two mold locking members 311 are activated, driving the first support member 11 and the third support member 13 to move downward relative to the second support member 12. At the same time, the two balancing members 321 are activated, and the second connecting member 331 balances the eccentric load of the mold locking members 311 on the first support member 11 to adjust the mold. During this period, the locking drive member 42 is not activated, and the brake nut releases the brake screw. After the mold adjustment is completed, the locking drive member 42 is activated, driving the brake nut to fix the locking brake screw. Then, the second support member 12 and the pressing member 22 together press the mold from the top and bottom of the mold to perform the mold locking operation.
